AV Module
The O2 is the first
workstation to integrate audio, video, and compression as the core
components of the architecture. The AV module and the O2Cam are included with O2 workstations bundled with video
configurations. The AV module performs all of the analog video and
audio I/O, and incorporates a video decoder, a video encoder, and an
audio codec. External AV connections are made through the side and
rear panel of the module. |

The O2 Digital Video Option module provides two input and output streams of
4:2:2 8- or 10-bit CCIR601/SMPTE 259M serial digital video. Both 525 and 625
timings are supported and either can be selected for input or output. A 4:0:0
alpha channel can be selected as one of the output channels, enabling a
real-time feed to an external downstream switcher/keyer. A highly accurate
genlock circuit as well as GPI I/O triggers are part of the advanced design.
The timings for the two outputs can be either free-running at 270MHz, locked to
input 1 or 2, or to the house sync input of the card.
